For the purpose of illustrating the application of my invention I haveshown a portion of a window which is designated by the reference numeralM). This window comprises a window frame i! having a stop l2 extendingabout the same and forming a rabbet H3 in which the storm sash M isreceived. This frame also provides a groove l5 in which the regularsliding sash of the window is disposed and which forms no particularfeature of the invention and has not been shown in the drawings. Only aportion of the sash it is illustrated namely one of the stiles itthereof which carries a pane of glass ll supported therein in thecustomary manner. The invention may also be used for screen sash and itis to be understood that where the word storm sash is used, a screensash is also intended.

In the use of the invention, preferably two sash stays and fasteners areemployed, one on each side of the storm sash. These sash stays and fas--teners are, however, identical in construction except that one is lefthanded and the other right handed and only that used on the left handside of the window has been illustrated and will be described. This sashstay and fastener comprises 40 a pair of jointed arms l8 and it whichare pivotally connected together at their joining ends by means of afriction joint 211. The arm it is pivoted to a mounting 22 secured tothe stile iii of sash it, while the arm I8 is pivoted to a mounting 23secured to the stop l2 of the window frame it. These parts will now bedescribed in detail.

The arm i8 is constructed from sheet metal and is stamped to provide ashank having circular ears 25 and 26 at the ends thereof. The 50 ear 25is pivoted to the mounting it which consists of a flat plate 2i of awidth equal to the width of the stop M. This plate is secured to thestop it by means of screws 28. Between the ear 25 and the plate 23 is afriction washer 29 which is 55 showing the constructed of fibre or someother similar material. A rivet 3| passing through the ear washer 29 andplate 21 and riveted over said plate serves as the pintle for connectingthe arm E8 to the mounting 23.

The arm I!) is constructed similar to the arm l3 and is formed with ashank 32 and circular ears 33 and 34 at the ends thereof. Issuingoutwardly from the end of the ear 26 of arm I8 is a strap 35 whichterminates in another circular ear 36. The strap 35 is bent U-shaped inform, as shown in Fig. 2, so that the ear 36 overlies the ear 26. Thecar 34 of arm I9 is disposed between the ears 26 and 36. Between thethree ears are arranged friction washers 31 and 38. A bolt 39 having asquare head 4| passes jointly through the ears 26, 34 and 36 and thewashers 31 and 38. The head 4| of bolt 33 is received within a squarehole in the head 26 and is held from rotation thereby. Upon the end ofthe bolt 39 is a nut 42 by means of which the joint may be tightened.Nut 42 engaging the ear 36 which is integral with the ear 26 is therebyprevented from rotating as the arms l8 and I9 swing relative to oneanother. The strap 35 is so arranged that the portion thereof,designated by the reference numeral 43, engages the edge 44 of arm |9and limits the opening movement of said arms so that the arms cannot bearranged with dead centers. This permits of closing the sash by merelydrawing on the pull thereof and without prior adjustment of the arms.

The mounting 22 is constructed in the form of a bracket from sheet metalwhich is stamped and bent to provide a base 45 and a flange 46 extendingoutwardly therefrom. Base 45 is adapted to be secured to the stile l6 ofstorm sash M by means of screws 41. The flange 46 of bracket 22, as bestshown in Fig. '7, is formed with an opening 48 which extends upwardlyfrom the base 45. The uppermost portion of this opening is reduced andformed in the shape of an arcuate groove as indicated at 49, whichgroove provides a bearing 5|.- The ear 33 of arm l9 has issuingoutwardly from it a pintle 52. This pintle is constructed with a spindle53 and a head 54 at the end of the same. The other end of the spindle isconstructed with a stem 55 which extends through the ear 33 and isriveted thereto. Head 52 is larger in diameter than the spindle 53 toprovide a shoulder 60. The extreme end of this head is tapered asindicated at 56. The opening 48, in flange 46, is of suitable dimensionsto permit of inserting the head 54 of pintle 52 through the opening. Thetapered end 56 of the head 54 facilitates such insertion. The spindle 53is of a diameter suitable to be received within the opening 49 and isguided for rotation in the bearing 5|. When the parts are applied, asshown in Fig. 6, the shoulder 60 prevents axial movement of the pintle52 in one direction and thereby prevents disengagement of the spindle 53from the bearing 5|.

For holding the spindle 53 in engagement with bearing 5|, a keeper isemployed which is indicated in its entirety by the reference numeral 51.This keeper is constructed from sheet metal which is stamped to providea body 58 pivoted to the base 45 of bracket 22 by means of a rivet 59.The body 58 has formed on it a head 6| which is offset from the plane ofthe base 45 and which is provided at its center with a groove 62. Groove62 is adapted to receive the head 54 and forms a further bearing for thepintle 52. This bearing, in conjunction with the bearing 5|, guides thepintle for rotation relative to the supporting bracket 22.

In order to force the pintle 52 into the groove 62, head 6| isconstructed with a cam 63. This cam is turned down to form a sloping camsurface 64, best shown in Fig. 3, which engages beneath the pintle 52and forces the said pintle upwardly into the reduced portion 49 ofopening 48 as the keeper is rotated. The outer surface 65 of the cam 63is arcuate to cause the same to clear the flange 46 of bracket 42, saidcam moving in close proximity thereto. The head 6| is also constructedwith a stop 66 which is adapted to engage the flange 46 of bracket 22when the pintle 52 is in engagement with groove 32 to limit furtherswinging movement of the keeper 51. The bracket 22 is preferablyarranged so that the stop 66 is uppermost whereby the keeper is heldthrough the action of gravity in proper position. The body 58 of keeper51 is provided with two upstanding lugs 61 and 68. These lugs are spacedapart a distance slightly greater than the width of the average screwdriver and are used for rotating the keeper 51. When the screw driver isplaced between these lugs and turned rotational movement is imparted tokeeper 51. The lug 61 is preferably constructed a little longer than thelug 65 so that the same may be grasped by a pair of pliers and thedevice rotated thereby instead of by a screw driver.

My improved sash stay and fastener is adapted to be locked in closedposition by the swinging of the two arms i8 and i9 jointly after thesash is in closed position. For this purpose the two arms 58 and i9 areof the same length from pivot to pivot and the pivots formed by pintle52 and rivet 3| are disposed so that the same overlie one another whenthe storm sash is closed. In addition, a lug 1| is employed whichextends outwardly from the arm l8 and which is adapted to engage theedge 12 of arm l9 when the two arms are brought together. into finalposition, this lug resists opening of the sash and holds the same inlocked position.

The method of installing and using the invention is as follows. Thestorm sash I0 is first closed, as shown in Figs. 2 and 3, and the twoarms i8 and is of the sash folded up and placed along the stop l2 andrail Hi. The fasteners may be arranged at any desired locality withreference to the hinge of the sash, it being borne in mind that thelower the disposition of the fastener the less the movement of the sash.While properly disposed the bracket 22 is secured to sash I4 throughscrews 41. The uppermost of the screws 28 is next applied .andthereafter the.

sash is openedand the lowermost of said screws is next applied. If twosash fasteners are employed, the other is similarly installed, carebeing taken to install the fasteners with the pivots of the bracketsthereof .at the same distance from the axes of the hinges of the stormsash. The arms l8 and IQ of the fastener are prevented from fullyopening by means of the corner 43 of strap 45 which engages edge 44 ofarm l9. By merely manipulating the sash through the pull attached to thelower rail thereof the sash may be opened and closed and the two arms I8and I9 follow the movement of the sash and swing from open to closedposition and vice versa. When the sash has been completely closed thearrangement of the parts is .as shown in Figs. 2 and 3. If it becomesdesirable to lock the sash, the two arms l8 and I9 are swung jointlyfrom the position shown in Figs. 2 and 3 to that shown When the arms areswung in Fig. 4. In the latter position the lug 1| pre-" vents openingof the arms and the sash remains locked in closed position.

When, at the end of the season, the storm sash is to be removed, thekeeper is swung by means of a pair of pliers or screw driver todisengage the pintle 52 from bearing 5i. Thereafter the pintle may beslid outwardly from the opening 48. This is accomplished by pressing thetwo arms l8 and I9 together. To facilitate such movement, the arm I8 isconstructed with an offset 73. Arms l8 and [9 may, if desired beconstructed with ribs H which stiffen the same. In Fig. 2 the keeper 5'!has been shown as swung away from the pintle 52, said pintle being in aposition to be disengaged from the bracket 22. A bracket similar tobracket 22 may be applied to the screen sash if a screen sash is to beused in place of the storm sash. The pintle 52 may be thereafter appliedto the bracket of the screen sash and the screen sash may then beoperated in identically the same manner as the storm sash.

The advantages of my invention are manifest. An extremely simple .andpractical device is provided whereby storm sash or screen sash may beheld in adjusted position in a manner such as to prevent rattling. Thedevice for holding the parts detachably connected is easi1y operated andwill not become unintentionally disengaged. The sash stay and fastenercan be constructed at a nominal cost. By means of the locking lugutilized the sash can be locked in closing position.
